一旦启用了xposed插件，wcdb就跑出异常，微信卡在启动时地球页面了。

微信版本6.6.1
VXP版本0.9.7
日志如下：

补充，手机是红米5A
Android系统 7.1.2
MIUI 9.5.3.0 稳定版

什么插件？

[captain-black]

自己的插件，禁用了某段操作微信打开WCDB的代码就可以了。裸xposed的时候代码没问题的，在vxp里就出问题，我先做了绕开处理了

[tiann]

@captain-black 能分享一下吗，是否跟提前加载了wcdb相关的类有关？

[captain-black]

在微信打开EnMicroMsg.db时，我hook来打印出数据库密码，没影响到微信的逻辑！ findAndHookMethod("com.tencent.mm.bw.a", lpparam.classLoader, "a", String.class, long.class, String.class, boolean.class, String.class, new XC_MethodHook() { @OverRide protected void afterHookedMethod(MethodHookParam param) throws Throwable { XposedBridge.log(TAG + "目标方法被调用: " + param.method.getName()); Log.d(TAG, "目标方法被调用: " + param.method.getName() + " 打开数据库"); Log.d(TAG, "---args---"); XposedBridge.log(TAG + " ---args---"); for (Object obj : param.args ) { Log.d(TAG, obj.toString()); XposedBridge.log(TAG + obj.toString()); } Log.d(TAG, "---args---"); XposedBridge.log(TAG + " ---args---"); } } );

[tiann]

也就是说，你之前直接hook了微信对数据库的打开操作，这样会有问题吗？

之前有人反馈 hook native/static 方法有bug，是否跟这个有关？

[captain-black]

就是以上代码引起了问题，注释了就正常了
